Tensor network simulation in strongly correlated systems: past, present and future
Abstract: Tensor network states are new kinds of variational wavefunctions that help us to understand quantum phases and phase transitions beyond Landau paradigm. In this talk, I will first review th...

Reachability analysis of quantum Markov chains and quantum Markov decision proce
Abstract: We introduce the notion of quantum Markov decision process (qMDP) as a semantic model of nondeterministic and concurrent quantum programs. It is shown by examples that qMDPs can be used in ...

Quantum Journal Club: Quantum Discord and the Power of One Qubit
Abstract: We use quantum discord to characterize the correlations present in the model called deterministic quantum computation with one quantum bit (DQC1), introduced by Knill and Laflamme [Phys. Re...

On the role of the general non-classicality of correlations in quantum informati
Abstract: Entanglement is considered the most characteristic trait of quantum mechanics. Nonetheless, almost all states---including unentangled ones---of bi-and multi-partite systems exhibit some qua...

Quantum Journal Club: Bose-Einstein Condensation of Atoms in a Uniform Potential
Abstract: We have observed the Bose-Einstein condensation of an atomic gas in the (quasi)uniform threedimensional potential of an optical box trap. Condensation is seen in the bimodal momentum distri...
